When I insert a date in Jooq, I get this error: column creation_date is of type timestamp with time zone but expression is of type character varying

Question

I'm using Spring boot and postgresql, this is my "pom.xml" file:

I want to insert a User object like this:

User:
  userId --> Long
  name --> String
  password --> String
  creationDate --> ZonedDateTime
  modifitionDate --> ZonedDateTime

In database:

Users:
  user_id --> bigint
  name --> character varying
  password --> character varying
  creation_date --> timestamp with time zone
  modifition_date --> timestamp with time zone

but when I try to insert the user:

@Autowired
DSLContext ctx;
...
Users users=Users.USERS;
ctx.insertInto(users, Arrays.asList(users.NAME, users.PASSWORD, users.CREATION_DATE, users.MODIFICATION_DATE))
   .values(Arrays.asList("user1","password",ZonedDateTime.now(),ZonedDateTime.now()))
   .execute();

I get this error:

column 'creation_date' is of type timestamp with time zone but expression is of type character varying

I realize that the Users class that jooq created has the "creation_date" field as "TableField<UsersRecord, OffsetDateTime>" type instead of "TableField<UsersRecord, ZonedDateTime>"

public final TableField<UsersRecord, OffsetDateTime> CREATION_DATE= createField(DSL.name("creation_date"), SQLDataType.TIMESTAMPWITHTIMEZONE(6).nullable(false), this, "");

I tried to convert the creation_date field from ZonedDateTime to OffsetDateTime before to putting it in the "values" method but it doesn't work either, I get the same error

What should I do to register the user correctly?

Answer 1

I think you need to add this parameter to the connection string: stringtype=unspecified

E.g: jdbc:postgresql://127.0.0.1:5432/testdb?stringtype=unspecified
